How the shape of a carabiner influences its breaking load

Slacktivity has conducted breaking load tests with pear-shaped and oval-shaped steel-carabiners to figure out how much tri-loading weakens carabiners.

    Not what I expected! Good old oval biners 🙂

      If the force of jumping on a slackline only exerts up to 13kN of force, I don’t think the difference between 25 and 50kN is that relevant! Nonetheless, gear wears and gets weaker with time, and poor equalisation of anchors is never a good idea.

    Nice! I hope my roadeavour is as good as that.
